So…according to reports, Katy Perry brought her on-again bf John Mayer home to her parents' house for Christmas. Holy huge step!

The singers dated earlier this year but allegedly broke up because John wasn't serious enough about the relationship. Apparently he got his act together because the two have been spotted together a bunch lately—en route to holiday parties and backstage at a Broadway show.

Katy even tweeted out a pic of her man dressed up as Santa Claus with the caption, "Santa Baby" on Christmas Day (check it out, left). Two things about that one: John was giving some serious bedroom eyes and whoa—getting a dude to dress up is hard enough; getting him to agree to let you post it online is another thing. It must be love.

But let's focus on what really went down here: Katy and John spent Christmas together. Where I come from, that's a BFD. Like, you don't bring a guy home for the holidays unless a) you've been together for ages, b) his family lives really far away and it would be cruel to leave him on his own for the holiday, or c) you're pretty damn sure there's a ring in your future.

It's worth pointing out, too, that last Christmas Katy was photographed frolicking in a Hawaiian sea, sans then-hubby Russell Brand. That all went down shortly before they announced their separation. We're glad to see that Santa brought her a better time this year.
